Application filed November '6, 1911. lSerial No. 658,827.

To'all whom it may concern:

Be it known that we, JOSEPH Panni and Gnsrav F. lfloornnnn, citizens 'of the United States, and residin atr Chicago. in the county of Cook and State of Illinois, have invented certain new and useful Improvements in Weighing Mechanism, of which the following is a speciIicat-ion.

This invention relates to weighing mechanisms which are joined to coin controlled mechanisms.

The object of 'this invention is to obtain sutlici'ent movement of certain elements of the weighing mechanism as to render the indicating elements of said weighing mechanism inoperative without that a coin is deposited `in the coin controlled mechanism which is joined to the weighing mechanism and certain detern'iined operations of said coin mechanism are performed. i i

A. further object of the invention is to obtain a weighing .mech-.mism provided with weighing beams having sliding weights4 thereon which when joined' to coin controlled mechanism, is not liable to get out of order, and which is accurate in operation,

vwhen a weighing is effected.

A further object is to obtain a weighing mechanism' which, when joined to coin controlled devices, operates to ascertain the `weight ot a person or thi-ng on the platform thcreo't in the same manner and with the same accuracy as do scales (having weighing beams) which are not designed to be so i4 further object is to obtain weighing .mechanism which cannot be gotten out of order during the operation or partial opera tion thereof or because of the failure to opcrate the coin controlled mechanism which is joined thereto.

A further object in the-'invention is toobtainv weighing mechanism provided with Q weighing beams and sliding weights thereon This devicev is embodied in scales which are provided with a base, a standard and a heath-the said base having therein -a weighing frame mounted in the ordinary way on weighing levers and a platform on said levers, the said standard hollow7 and having therein a longitudinally movable rod and the said head having a scalewith two members exposed to view, mounted in the ordinary way and provided with sliding weights, the said longitudinally movable rodv connected at its lower` end to the weighing levers and at its upper end to the scale beam in the ordinary way, totransmit motion of the weighing frame to the .scale beam.

ln the drawings Figiire l is a. perspective view of a weighing scales with the deviceA embodying our invention applied thereto.-

Fig. 3 is an edge view of a plate which is attached to the head of the scales and of a vertically movable rod mounted on said plate showing a small portion of two of the members of the weighing beam in elevation. front elevation of the plate and rod which are illustrated in Fig. 3, showing th'e two 5 is a plan view of the base and platform ot a scales, showing a horizontal sectional view of the standard of Ythe base .with the plat.- form illustrated in Figs. 7 and 8,v thereon and with the operative mechanisms in said base indicated by broken lines. Fig. 6 is a vertical sectional view of the base, of the scales, the platform and the standard thereof and the weighing levers, weighing. beams and remaining operative parts which are located in said 'base and standard. Fig. 7 is a vert-ical viewof a portion of the Weighing trame of av scales to which the device embodying our invention is joined and of the platform and connections forming a part of our invention which is mounted on said weighing frame.

bars "t said frame shown in vertical section. Fig. il is a top plan view of the central bar of the weighing frame and of a portion of the end bars of said frame, Figs. 12 and 13 are, respectively, side elevations of levers pivotally mounted on the central bar ot' the weighingframe. Fig. 14 is an end elevation of a modification oi the platform of the device and a lever thereon, forming elements in the device embodying our invention. Fig-1 5 is a 'front elevation of the modification illustrated in Fig. 14. Figs. Q, 3, 4, and 7 to 15, (both inclusive), are on an enlarged scale :trom Figs. 1, 5, and 6.

Similar letters refer to throughout. the several views: p

X is the base, Y the standard and Z the head of the scales to which we have applied our invention.

X, 5 and' 6,are the weighing levers and X the weighing frame of the scales.

Y is the connection joined aty its lower end. (see Figs. aand 6), to the weighing lever X and at upper end (see Fig'. 2) to the'vveighing beam.

Z, Z and Z are members of the weigh ingl beam, and are provided with sliding` weights Y and YW in the ordinary wav Weighing' levers X and the weighing frame X" are mounted in the ordinary way7 relative to each other and to the` base X, as well shown-in Figs. 5 and 6. The connection Y is theordinary Connection between the weighing levers of a scales and the weigng eam thereof and the weighing heam,monnted as shown and provided with inemb rs Z', Z", Z is well known and forms no part of our invention. As no change is required or made by us inthe mounting of these parts of a scales we can apply the device embodying our invention to any weighing scales of the type illustrated. n

As We do notdesire the scales to which our device is applied to be adjusted (for accuracy) by the person using the same, we

similar parts -inount the adjusting screw ZV on member Z of the Weighing beam so that it is rotatable, (see Fig. 2), and non-rotatably mount the adjusting Weight Z on said members Z and oli-said screw Z. Screw Z is not movable longitudinally, while weight Z is movable longitudinally. TurninfaY the screw Zf, therefore. slides the weight Z to accurately adjust the scales. l

That portion of the mechanism Vwhich forms a part of the device embodying our *invention which is positioned in or on the biise X consists of a platform (A), which is mounted. on the Weighing frame X to which- `are niovably mounted on the central bar of the weighing frame. Platform A (Figs. 1, 5,16; 7, 8, and 9.), is pivoted at B (Flgs. 6 mid -7)' to weighing frame X and is yieldingly held in a determined position relative to said weighing frame by spring b.

Bolt b .limits the movement of platform A said platform, while said platform at the end of said movement rests firmly on the weighing frame beam and the same eti'ect, so tar as ol'itaining the weight oi the person or thing' on the platl" ii'1ii, is obtainable. as it said platform were integral with the weighing frame, as in the ordinal-v construction.

Levers C, l). are pivotally mounted on the cen 'c bar X ot the ive-igl'xingg` trame X at G and D, respectively (see Fics. (l and io). with. each other at their adjacent end as by forli E ot lever C having end c ol" lever D therein.

F (Figs. G and is a spring' connected atone end to weighing frame X and at the other end to lever l), `vieldinirly holding up the end ot said lever which said spring! is connected to. The -free end ot hoer C is yieldingly held near to the um'leitside o'l` the platform A., b v spring F acting on lever l), as described, and hence said lever C is moved on its pivot C b v the movement et plat-form A on its pivot B, when a person steps on said platform or deposits a thing;V there m to be weighed. Movement oi' lever C on its pivot C moves lever D on its pivot D, so that the free end of said lever D moves downward and the connection Y which is connected at its lower end with said lever l) is moved longitudinally downward thereby. i

'The several. parts of the scales exceptthe weighing beam and the mechanism forming' elements in e. device embodyingour invention which are located in the base and standard ot' the scales are operative and operate in the same wa)v (and as hereinbefore described) whether a coin (deposited in the slot which is provided therefor in head Z) is in the runway ct the coin controlled device or not. and the lever G which is heated `in head Z, and is a. part of the coin mecha- Levers C and D are in engagementits upper endi in a horizontal plane. which is longitudinally movable in bearings. l on plate J (see Fig. 3).
